When I came into the 21st century and stopped fooling around with my hundreds of CD’s and LP’s and started streaming music it was a veritable godsend. I use a ROON Nucleus Rev B to stream music from Tidal and Qobuz. My router is a Gigaspire model made by Calix that was provided by my cable TV internet service, a product which I plan on upgrading in the future. I use a $20 CAT6 Ethernet cable made by L-Com running from the router to my Nucleus, because there is no need for a more expensive one unless you have a much better router. I do use an AudioQuest Diamond USB cable from the Nucleus to my ROON endpoint, a Chord Hugo M Scaler, because I’m not a cable denier, and the AQ Diamond is one that sounds quite nice within my listening chain. I’m all about plug and play convenience. I turn on my Woo WA22 hp amp, put my Focal Utopia headphones on my head, pick up my iPad Pro, and start listening to whatever recorded music suits my fancy. It’s that easy. You can spend thousands on TOTL streaming audio gear if you want to, but it really isn’t necessary if you’re just getting started.
